VETERINARY. INSTRUMENT.

Specification of Letters Patent.

Patented Oct. 8,1912.

Application filed February 12, 1912. Serial No. 676,975.

To all whom it may concern:

Be it known that I, SWINEA OLsoN, a cit-i zen of the United States,residing at Amboy, in the county of Blue Earth and State of Minnesota,have invented a new and useful Veterinary Instrument, of which thefollowing is a specification.

This invention relates to improvements in veterinary or obstetricalinstruments.

The object of the invention is to aid the operation of veterinaryparturition, particularly in delivering sows of their young, while it isserviceable for a like purpose in connection with other animals.

A further object is to greatly simplify the aforesaid operation and toeffect carrying out the same with the minimum inconvenience and distressto the animal, and to readily accommodate the application of the deviceto the position of the young, whether regular or irregular, or othercontingencies. A still further object is to provide for performing theaforesaid objects in an expeditio-us and effective manner.

The invention consists of slender members adapted to pivot one upon theother, and a lasso-like flexible member carried by said members, andunder the control of the op erator for manipulating the same, throughthe assistance of said members, in securing a hold upon the object oryoung with the view of its delivery or extraction.

In the accompanying drawing illustrating the preferred embodiment of myinvention wherein it will be understood that various changes andmodifications as to the detailed construction and arrangement of theparts may be made without departing from the spirit thereof, Figure 1 isa perspective view of the device. Fig. 2 is a like view, showing thedevice in operative position. Fig. 3 is a fragmentary perspective viewdisclosing more fully the latter position of the device. Fig. 4 is asectional view taken on the line w-w of Fig. 2.

In carrying out my invention, I employ two metal members 1 and 2, thesame being quite slender and having threaded through apertures or eyes 3and 4: therein respec' tively, a flexible or string member 5, secured orknot-ted at one end against casual escape from the eye 3, at the extremeforward end of the member 1. The member 2 has its forward end extendinga short distance, as at i 6, beyond its eye at for entering the vaginalpassage of the animal and carrying the loop formed in the string orflexible member 5 and passing the loop around the young, said forwardend portion 6 being suitably rounded for obvious reasons.

The member 1 has suitably pivoted thereto near its rear end a couplingbar or latch 7 itself havinga stud or projection 8 adapted to bereceived by an aperture or passage 9 formed in the member 2, near thecorresponding end thereof, for effecting, as indicated, the couplingtogether of said members 1 and 2 and to provide for the suitablerelative movement and guidance thereof in manipulation of the device, inintroducing or inserting the member 2 with the 100 of the string orflexible member 5, as wil be readily appreciated by those familiar withthis class of devices.

It will be noted that, with the member 2 suitably grasped and held byone hand of the operator, in alinement wlth the axis of the vaginalpassage, and the other member 1 grasped and manipulated by the otherhand, with respect to the member 2, a loop 10 may be formed in thestring 5 and that, by suitably introducing the forward end portion 6 ofthe member 2, together with said loop into the vaginal passage and so asto effect passing the loop over the head of the young, the required holdmay be obtained thereon, by suitably actuating the string, for effectingthe delivery. These ma nipulations may all be performed, it is apparent,without any appreciable distress or discomfort to the mother-animal,while the oung is readily reached and delivered without liability ofinjury, whether it be in regular or irregular position during theparturition operation.

WVhat is claimed is:

A device of the type described, including members having eyes therein,one of said members having a forwardly projecting portion beyond itseye, one of said members the head of having a coupling member pivotedthereto as my own, I have hereto alfixed my signaand gdapted to beiengalged With the other ture in the presence of tWo Witnesses.

meln er and a feXib e member passed through said eyes, one end of saidflexible SWINEA OLSON member being-held to one of the first-re-Witnesses: ferred to members. C. D. OTT,
